You are encouraged to solve this task according to the task description, using any language you may know.
Every connected device around the world comes with a unique Media Access Control address, or a MAC address.
A common task a network administrator may come across is being able to identify a network device's manufacturer when given only a MAC address.
- Task
Interface with one (or numerous) APIs that exist on the internet and retrieve the device manufacturer based on a supplied MAC address.
A MAC address that does not return a valid result should return the String "N/A". An error related to the network connectivity or the API should return a null result.
Many implementations on this page use http://api.macvendors.com/ which, as of 19th September 2021, is throttling requests. After only 2 calls, the following response is returned for all subsequent requests. If you are planning to use the same provider or going to run the examples on this page, consider building in a delay between two calls.
{"errors":{"detail":"Too Many Requests","message":"Please slow down your requests or upgrade your plan at https://macvendors.com"}}

APL
Normally something like this would just be mapping the lookup across an array, but that doesn't let us control the timing of the request dispatch. To insert a delay between requests we have to create a traditional function ("tradfn") with a for loop.
⍝load the library module
]load HttpCommand
⍝ define a direct function (dfn) to look up a single MAC address
vendorLookup1 ← { (HttpCommand.Get 'http://api.macvendors.com/',⍕⍵).Data }
⍝ define a traditional function to look up all the MAC addresses in a list with
⍝ a delay between calls
⍝ The header says that the function is named vendorLookup, it takes a single
⍝ parameter which we call macList, and the value of the local variable
⍝ vendors will become the function's return value
∇ vendors ← vendorLookup macList
⍝ look up the first vendor and put it into an array in our return var
vendors ← ⊆vendorLookup1 1↑macList
⍝ Loop over the rest of the array
:For burger :In 1↓macList
⎕DL 2 ⍝ wait 2 seconds
vendors ⍪← ⊆vendorLookup1 burger ⍝ then look up the next vendor and append
:EndFor
∇
⍝ demo data
macList ← '88:53:2E:67:07:BE' 'D4:F4:6F:C9:EF:8D' 'FC:FB:FB:01:FA:21'
macList ⍪← '4c:72:b9:56:fe:bc' '00-14-22-01-23-45'
⍝ look up the vendors (takes a while with the 2-second delay between lookups)
vendorList ← vendorLookup macList
⍝ the result is an array (a 1-row by N-column matrix). to print out one vendor
⍝ per line, we reshape it to be N rows by 1 column instead.
{(1⌷⍴⍵) 1 ⍴ ⍵} vendorList

AppleScript
set apiRoot to "https://api.macvendors.com"
set macList to {"88:53:2E:67:07:BE", "D4:F4:6F:C9:EF:8D", ¬
"FC:FB:FB:01:FA:21", "4c:72:b9:56:fe:bc", "00-14-22-01-23-45"}
on lookupVendor(macAddr)
global apiRoot
return do shell script "curl " & apiRoot & "/" & macAddr
end lookupVendor
set table to { lookupVendor(first item of macList) }
repeat with burger in macList's items 2 thru -1
delay 1.5
set end of table to lookupVendor(burger)
end repeat
set text item delimiters to linefeed
return table as string
If this is part of a larger script you probably want to save and restore the text item delimiters:
set savedTID to text item delimiters
set text item delimiters to linefeed
set tableText to table as string
set text item delimiters to savedTID
return tableText

UNIX Shell
Surprising that nobody had implemented the Bash / Shell version yet.

}
lookup "${macList[0${ZSH_VERSION:++1}]}"
for burger in "${macList[@]:1}"; do
sleep 2
lookup "$burger"
done
It can be made to work in a pure-POSIX shell without array variables:
set -- 88:53:2E:67:07:BE D4:F4:6F:C9:EF:8D FC:FB:FB:01:FA:21 \
4c:72:b9:56:fe:bc 00-14-22-01-23-45
lookup() {
curl -s "http://api.macvendors.com/$1" && echo
}
lookup "$1"
shift
for burger; do
sleep 2
curl -s "http://api.macvendors.com/$burger" && echo
done
And hey, just for completeness, let's toss in a [t]csh version:
set macList=(88:53:2E:67:07:BE D4:F4:6F:C9:EF:8D FC:FB:FB:01:FA:21 \

alias lookup curl -s "http://api.macvendors.com/!":1 "&&" echo
lookup "$macList[1]"
foreach burger ($macList[2-]:q)

Wren
Wren CLI doesn't currently expose a way to look up a MAC address.
However, if Wren is embedded in (say) a suitable Go program, then we can ask the latter to do it for us.

class MAC {
foreign static lookup(address)
}
System.print(MAC.lookup("FC:FB:FB:01:FA:21"))
for (i in 1..1e8) {} // slow down request
System.print(MAC.lookup("23:45:67"))which we embed in the following Go program and run it.
/* mac_vendor_lookup.go */
package main
import (
wren "github.com/crazyinfin8/WrenGo"

"net/http"

type any = interface{}
